3-Acetoxyamino-2-trifluoromethylquinazolin-4(3H)one as an aziridinating agent for alkenes
Abstract
The title compound 4, prepared by lead tetraacetate oxidation of 5, is stable at room temperature and aziridinates alkenes in better yield and higher diastereoselectivity than, e.g. the 2-ethyl compound 1; hydrazinolysis of the quinazolinone ring in 20 gives the corresponding N-aminoaziridine 21 in 64% yield.
